Fig. 3 shows the device 'ii'1 elevation I I holding alamp, vIn' Y "ment the lamp is shown-in soli-dlines. In a differentipositionthe lamp is indicated by dotted lines. Fig. 4 shows in perspective thesocketelement direotly engaged by the lamp with'thejadjnsting mechanism, all of which goes inside of the casing,

Fig; 8 is aline 88, Fig. 1', showing the relative posi- "easing, This section is 15, Fig.5, a I v Referring in detail to theadravvlng, the device comprises a casing 2, Fig.1, of lnsulating taken along the teeth to material, on the top of which -there may be ich modifies the light produced, by thelamp'; It is an objectof my 10 inventiomtherefore, vieewhich maybe;readilyadjusted.asfor felxample the manipnlation ofthe. lamp the form of a screw,

will be inrderstood," 20 however that :I do notfwfish to be limited to one position, of, adjnst Figs. 1 and 2., Fig. 5 is a so-called exploded view of the ele-I longitudinal. section" on tions of the element's-of thesocket and the for the spring 16 of Fig minals 3 and 4. In Fig; 4 the lamp engag ng socket element '5 is shown in operative en 1 central contact e'lement 7 inthis figureis con nected bymeans of a fiexible conductor 8 with a screw or bolt 9 which also'servestoelamp the plug terminal l to the casing '2. "Similar ly, the outer, or shell, contact 5. whieh is in; is connected by means of a flexible condn'ctor 10 with theboltll, which latter serves to clamp the terminal 3- to the 1 casing 2. The bolt 11 e150 serves-to clamp device to the oas-" 2-,- liewnl tween the rack Gof the adjnsting ing 2'. Referring to Fig. that the casing 2 is provided on" the inside f with a channel 12,1wrthin which-the raek- 6 is located. In section; the rack is ch'annelshaped, the teeth13 beingfor1ned along one of the edges of the channel; 'Thefshell-oontact 5 is provided, asshown,"witha-set of one or more-teeth 15 adap'tedto engagetheteeth 13 in the rack. The; spring element 16} one end '17 of-the which is secured to the flangei l l and therefore to theshelli 5 at a point just behind'the teeth15,'oonstitntes a resih ntmeans which normally operates 15 into engagement 'with the; teeth 13; It

Will be nderstood thatthe 1eg'18 'of'the' 8 0 spring engages the side 19 of t-he channel {ele+ 'ment 6 behindthe flange 20. ,In adjusting to force {the teeth the device the springlfi'isrcompressed byro; l

teeth are thus disengaged; obvionslythelamp and itssocket may be slid'in the'casing2 nn til the proper position for the lamp is reached; I

At this polnt the lamp is released an-d the tensenor thespring 161willforce1theteth lfi f I back intofengagement with the rack .GI-there} by looking the lamp in-p'osition;

It will be seen thatthe devices,"'-Figs'.i6 and *7, aresub'stanti'ally the same as'those 'shown in Figs. 4 and 5, thedifierenoe being that the flange 20 of the rack 'fi is omit-ted; and-'aidifferent' form' of spring device-is 's' ibstituted 5.9 This devieeoomprises a' bar 21 and a spring22, the ends 23 7 one, position in casing '2. to a new and 24 of which engage the side 25 of the rack 26. In the device of Fig. 7 the teeth 15 of Fig. 5 are replaced by a rack element 28 secured to the side of the shell, the rear surface 29 of which is maintained in engagement with the side 30 ofthe bar 21. Obviously, by rotating the lamp in the direction indicated by the arrows, Figs. 6 and 7, the rack 28 is forced to compress spring 22, with the result that the teeth 28 disengage the rack teeth 31. Under this condition the lampmay 'be raised or lowered and when the rotary pressure 1s released, the spring 22 willagain bring the teeth of the rack 28 into engagement with the teeth 31 of the rack element 26, thereby lockingthe lamp its new position.

vvitha device of this construction it is ob V viousthat an incandescent lamp, such as lamp may be easily and eadi y adjusted from position by p and down the direction of the axis of the lamp until the idesi red position is reached, as for example, from the position indicated by the dotted lines of Fig. ,3 to that repreel ed by he s lid line As i e l HD 6 stood,.t;hecontacts Bjand, when .the socket is in use, are separated by means of a cutout film between the upper ends thereof as indicated in Fig. 3, V

What I clainras new and desire to secure by Letters Patent of the United States, is In combination, a lamp socket, a casing for the socket, and latching means within said casing interposed between the casing ands 'id kt whereby the cke ay e tmlatched adjusted, and latched again with espec o he ca ing.- g
